Description

BACKGROUND OF THE INVENTION

The present invention relates to a ramp system for sports and, more particularly, to a combination ramp system for sports.

China Patent Application No. 201821106343.6 discloses a sport equipment overlap joint bridge and combination with ramps thereof including a top face and a bottom face. The top face is provided with a first end and a second end opposite to the first end. The bottom face is projectingly provided with a first positioning column and a second positioning column. The first positioning column is adjacent to the first end, and the second positioning column is adjacent to the second end. One end of the first positioning column opposite to the top face is projectingly provided with a first threaded column. One end of the second positioning column opposite to the top face is projectingly provided with a second threaded column. The first threaded column is threaded connected with a first fastening member and sleeved with a first anti-loose member disposed at a side of the first fastening member opposite to the top face. The second threaded column is threaded connected with a second fastening member and sleeved with a second anti-loose member disposed at a side of the second fastening member opposite to the top face.

However, when the above overlap joint bridge is assembled between two ramps, the two ramps must be quite close due to the size of the overlap joint bridge. If the size of the overlap joint bridge is increased, the overlap joint bridge will easily depressed or even break due to the weight of the user.
